0. Quasi-likelihood parameter estimation- The package provides methods for parameter estimation for statistical models that can be simulated. We follow a quasi-likelihood approach to estimate the unknown parameter by the root of the so-called quasi-score estimating function.

3. spsextante - R to Sextante interface- Provides a suite of geospatial analysis tools by connecting R with the Sextante geograrphical information system (www.sextantegis.com), similar to spgrass6 and RSAGA.
